OIL-DISTRIBUTING APPARATUS FOR CALMING WAVES.

SPECIFICATION forming part of Letters Patent No. 710,013, datedSeptember 30, 1902.

Application filed September 28, 1901. Serial No. 76,936. (No model.)

To all whom it may concern:

Be it known that I, NILS SALVESEN, a subject of the King of Sweden andNorway, residing at Grimstad, Norway, have invented certain new andImproved Oil-Distributing Apparatus for Calming Waves, of which thefollowing is a specification.

I have by trials on the sea invented a device by which I am able to workbags or vessels filled with oil for sea-calming purposes from the shipagainst the wind to any desirable distance from the ship.

I carry out my invention by employing a floating body and provide thesaid floating body with suitable means'for instance, a loop, or a ring,or a tail-blockthrough which I pass a cord, rope, or the like. When thecase arises that it is desirable to break the waves, I throw overboardthe floating body, let the vessel drift, all the time paying out thecord or rope, until the vessel has drifted the desirable distance fromthe floating body. I now stop paying out the cord, and having fastened abag or vessel filled with oil to the one part of the running cord I amable to work the said oil-filled bag or vessel to any desirable distancebetween the vessel and the floating bod y. When the bag is empty, I haulit back, at the same time sending out a fresh bag filled with oilattached to the other part of the line. For safetys sake and also forthe easy working of the running line I have fastened to the floatingbody the one end of a hawser, the other end of which is fastened to thevessel. By this means I am able to keep a steady supply of oil on thewindward side of the vessel and at such a distance from the vessel thatthe oil will act in the most efficient manner.

In order to more fully explain my invention, I refer to the appendeddrawings, on which I have shown a suitable form of my device in which abag of canvas or other suitable material forms the floating body.

In the drawings, Figure 1 shows the said floating body in elevation;Fig. 2, same in front view, and Fig. 3 is a plan view showing the way ofworking oil-filled bags or vessels between a ship and the said floatingbody.

As mentioned above, the floating body is made in the shape of a bag ofcanvas 0;, which is open in front and provided in the bottom with asmall aperture 1). The said aperture is provided in order to reduce thepressure of the wateron the bottom of the bag and also for the purposethat the jet of water produced through the said aperture shall steer thebag and give it a steady motion in the water. The foremost end of thebag is kept expanded by any suitable meansfor instance, a solid ring 0,to which the edge of the bag is fastened in any suitable manner. The bagis at the middle and at the hind end near the bottom provided with rings(1 and e, of slightly less diameter than ring 0 for the purpose ofkeeping the bag in an expanded state. However, the arrangement of theselatter rings 01 and e is not considered to be necessary because thepressure of water will be quite sufficient to keep the bag in anexpanded state. The ringc might be provided with eyes 8, in which theend of the hawser from the vessel should be fastened. The bag a isfurther provided with swimmers f, which by means of a cord g areattached to lugs h and j on the top of the bag a, the object of theswimmers being to keep the bag suitably immersed in the water and alsoto prevent the turning of the bag at around its longitudinal axis. Inorder to further prevent any such turning, the bag is provided with aballast-rod it, supported in lugs Z and m at the under side of the bag,the said rod having a head 'n in the one end and in the other a hole inwhich to insert a splint 0, whereby the rod is kept in place. The bag ais on its sides provided with lugs 19 and q, fastened to the rings 0 ande for the purpose of attaching the running line 7, with which theoil-bag u is to be worked, between the vessel and the bag a. Of coursethe line r might as well run in tail-blocks fastened to the bag a.

Supposing the vessel at the point t, Fig. 3, is overtaken by stormyweather or any mishap occurs, the bag a is attached to a hawser andaline is passed through the lugs 19 and q, whereupon the bag is thrownoverboard. While the vessel is drifting off, the direction of the windbeing indicated by the arrow, the hawser and the line 0 are paid outuntil the vessel has reached a suitable distance from the bag. Thehawser is now fastened to the side of the vessel and an oil-bag isattached to the one part of the running line r and hauled out tothedesired distance from the vessel. Now when the weather has calmed or theaccident has been remedied the pressure maintained by the line connectedto ring 0 is released, when the bag will collapse, the same being hauledinto the ship by pulling in the running line 1', connected to ring 6.

Having now described and ascertained the nature of my invention and inwhat manner the same is to be carried out, I declare that what I claimas new, and desire to secure by Letters Patent, is-

1. In a device of the character described, a collapsible bag, a seriesof suitably-spaced annular rings of slightly-varying diameter secured tosaid bar, one of said rings being secured at the forward end and one atthe rear end of said bag, said bag to the rear of said last-named ringhaving a contracted opening therein, lugs carried by the said rings,means secured to said lugs and extending in alinement with the length ofsaid bag for preventing the bag from turning ox'er on its lon- 1gitudinal axis, and means connected to said forward ring for connectionwith the vessel, substantially as described.

2. In a device of the character described, a collapsible bag, a seriesof rings secured to said bag for retaining the same in an expandedconical shape, one of said rings being secured to the front end and oneto the rear end of the bag, said bag having a tapering extension with anopening therein beyond said rear end of the bag, lugs secured to therings on the under side thereof, a ballast-rod secured in said lugs andextending the length of the bag, swimmers carried by the said lugs, andmeans for connecting the bag to the vessel, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
